This question is logically problematic. If everything needs a creator, than no matter what exists, it must have been created. Furthermore, to be created means that someone or something had to create it. But then, who created the creator and so on? Logically, this would mean there would be an infinite regression of creators (prior causes), and we would never be able to find the first uncaused cause since by definition (the question says that "everything needs a creator") there wouldn't be any uncaused cause. This would mean that the sequence of creations is eternal. But, if it exists that there is an eternal regression of creators, then who created the infinite regression of creators? Remember, the question presupposes that all things need a creator--even the eternal sequence of creators--which becomes logically absurd. Furthermore, if there is an eternal regression of creators that are eternal, then the question is not answered. In fact, it cannot be answered since its weakness is that "all things need a creator." Of course, this only begs the question in that how did the process begin? Therefore, the question only raises the same problem it asks, and it is a question that, by its own design, cannot be answered. Therefore, it is invalid.
The question is better phrased as a statement: "Everything that has come into existence was brought into existence by something else." This is a more logical statement and is not wrought with the difficulties of the initial question. In the revised statement, "Everything that has come into existence" implies that the thing that "has come into existence" did not already exist. If it did not already exist but then came into existence, then something had to bring it into existence because something that does not exist cannot bring itself into existence (a logical absolute). This pushes the regression of creators back to what we would call the theoretical "uncaused cause" since there cannot be an infinite regression of creators as discussed above and since an infinite number of creators would mean there was an infinite number of creations and created things, including things that cannot be destroyed since they would constitute things that exist. If that is so, then the universe would have had an infinite number of created things in it; and it would be full. But it is not full. Therefore, there has not been an infinite regression of creations.
By definition, the Christian God never came into existence; that is, He is the uncaused cause (Psalm 90:2). He was always in existence, and He is the one who created space, time, and matter. This means that the Christian God is the uncaused cause and is the ultimate creator. This eliminates the infinite regression problem.
Some may ask, "But who created God?" The answer is that by definition He is not created; He is eternal. He is the One who brought time, space, and matter into existence. Since the concept of causality deals with space, time, and matter and since God is the one who brought space, time, and matter into existence, the concept of causality does not apply to God since it is something related to the reality of space, time, and matter. Since God is before space, time, and matter, the issue of causality does not apply to Him.
